after sean at hemifever tuned my truck he said i will want to look into a catch can. i have noticed on the forums everyone is saying the 07 hemi has a internal pcv. so how do i go about doing this? my idea was just to take the hose coming off the oil fill and put a small breather on it, wile caping the inlet on my cai. will this idea work? if not what should i do. Also at 21k when i pulled the stock intake to install my cai my throttle body was a clean as could be.

I'm not real familiar with that pcv system on that engine, but that doesn't sound like it's the pcv valve. I have also always heard the pcv is internal on 3rd gen hemi's. Which makes me wonder how you change the valve...
